Análise não linear geométrica do acoplamento solo-estrutura através da combinação MEC-MEF

Autor: Silva, Wagner Queiroz

Neste trabalho foi desenvolvida uma formulação alternativa para o acoplamento entre o método dos elementos de contorno (MEC) e o método dos elementos finitos (MEF) para análise não linear geométrica de estruturas reticuladas ligadas a meios co

Structural analysis of a sail solution1 to deorbit satellites is presented in this paper. The deployable drag sail consists of a circular highly flexible frame, sail and housing. The folding process of the highly flexible frame is complex and is only

As wind turbine blades are getting longer and more slender, new failure modes occur and these may be related to the non-linear geometric Brazier effect1,2,3, where the bending moments ovalize the thin-walled cross-sections. For general cross-sections

Aerodynamic Decoupled FDI for Frequency Faults in Earth Satellite Engines

Autor: P. Baldi, Paolo Castaldi, Nicola Mimmo, Silvio Simani

Publikováno v: IFAC Proceedings Volumes. 45:1095-1100

This paper presents new results regarding the development of a fault detection and isolation scheme for a nonlinear satellite model. The main issue concerns the handling of frequency faults affecting the reaction wheels of a spacecraft attitude contr
